Abstract
The utility model discloses a kind of plug-in type crosspointer microwave coagulation devices for hepatectomy, including a handle, ablation needle, waterpipe jointing and microwave cable interface are installed on handle, coaxial cable is provided in ablation needle, the front end of ablation needle is equipped with microwave radiation device, and coaxial cable includes inner conductor and outer conductor, and insulator is provided between inner and outer conductor, microwave antenna is provided in microwave radiation device, microwave antenna is connected with inner conductor.The advantageous effects of the utility model are: 1, when operative region is larger, carrying out solidifying-lock out operation on pre-cut face repeatedly using microwave coagulation antenna, can complete operation excision.2, the tissue and 2mm blood vessel below that can solidify target area, avoid the expansion of solidification zone, advantageously reduce the generation of the relevant complication of postoperative ablation.
Description
Technical field
The present invention relates to a kind of microwave coagulation antenna more particularly to a kind of plug-in type crosspointer microwaves for hepatectomy
Coagulation system.
Background technique
Liver is the vitals of human metabolism, has Quadruplet pipe road system for receiving and exporting blood, therefore,
Liver is a multivessel organ, is caused when carrying out operation on liver, and bleeding is easy to happen, and hepatectomy is high one of difficulty
Kind operation.
Classical hepatectomy, which need to be blocked frequently, cuts liver into hepatic blood flow, then row clamp method.Currently used for auxiliary hepatectomy
Principle of instrument is related to ultrasonic energy, high-frequency energy, radio frequency etc., wherein the combination quilt of ultrasonic suction knife (CUSA) and bipolar coagulation
Be considered most perfectly to combine: while CUSA smashes liver organization, bipolar coagulation solidifies the blutpunkte on liver section, completes
Hepatectomy.Even if average each hepatectomy amount of bleeding can also reach 600~1000ml in the case of having advanced instrument auxiliary.
In addition merging the hepatotomy of cirrhosis is still a problem for surgeon.On the one hand, ultrasonic suction knife (CUSA) is uncomfortable
Liver with cirrhosis is answered, on the other hand, frequently example is stopped to enter hepatic blood flow, will lead to major Liver ischemical reperfusion injury, will increase
The occurrence probability of the liver function decaying of liver with cirrhosis.Meanwhile when carrying out malignant tumor of liver excision, ultrasound knife, CUSA and electricity
Knife is difficult to cut off borderline tumor completely, be easy to cause residual tumor, postoperative to be easy to appear tumor recurrence.
Hepatectomy is assisted to solve the above problems, can research and develop using radio frequency and microwave energy.
Summary of the invention
The purpose of the present invention is to provide a kind of plug-in type crosspointer microwave coagulation devices for hepatectomy, solve existing
There is shortcoming existing for technology.
The present invention adopts the following technical scheme that realization:
A kind of plug-in type crosspointer microwave coagulation device for hepatectomy, which is characterized in that including a handle, institute
It states and ablation needle, waterpipe jointing and microwave cable interface is installed on handle, be provided with coaxial cable, ablation needle in the ablation needle
Front end microwave radiation device is installed, the coaxial cable includes inner conductor and outer conductor, is provided between inner and outer conductor
Insulator, is provided with microwave antenna in the microwave radiation device, and the microwave antenna is connected with inner conductor.
Further, the ablation needle is two, and the diameter of ablation needle is 2mm, length 100mm, between ablation needle
Distance is 15mm.
Further, it is provided between two ablation needles and block is auxiliarily fixed for fix ablation needle.
The method have the benefit that: 1, when operative region larger, using microwave coagulation antenna repeatedly in pre-cut
Except carrying out solidifying-lock out operation on face, operation excision can be completed.Because excision is carried out in tissue coagulation area, for swollen
For tumor excision, especially for the excision of the nearly tumour of pre-cut face paste, this operation improves operation for reducing residual tumor
Radical rate is beneficial；2, the tissue and 2mm blood vessel below that can solidify target area, avoid the expansion of solidification zone, have
Conducive to the generation for reducing the relevant complication of postoperative ablation.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
By the following description of the embodiment, the public understanding present invention will more be facilitated, but can't should be by Shen
Given specific embodiment of asking someone is considered as the limitation to technical solution of the present invention, the definition of any pair of component or technical characteristic
Be changed and/or to overall structure make form and immaterial transformation is regarded as defined by technical solution of the present invention
Protection scope.
Appended drawing reference: ablation needle 1, ablation needle 2, handle 3, microwave cable interface 4, waterpipe jointing 5.
As shown in Figure 1, plug-in type crosspointer microwave coagulation device includes handle 3 and two ablations being in a row fixed on handle
Needle 1 and ablation needle 2, ablation needle include ablation syringe needle and shank, and the inside of ablation needle includes coaxial cable and cooling water pipe, handle
The 3 shell composition by microwave high-frequency connector, cooling system, power splitter, and set outside.Be connected on handle 3 outlet pipe and into
Water pipe, interior handle 3 includes microwave power distributor and inner water-tank, connects the cooling chamber in handle 3 and ablation needle, uses circulating chilled water
Handle and ablation needle are cooled down.Each ablation needle is made of the microwave radiation device of coaxial cable and front end, coaxial electrical
Cable includes inner conductor and outer conductor, and insulator is provided between inner conductor and outer conductor, and microwave radiation device is provided with microwave day
Line, microwave antenna are connected with inner conductor, one are equipped between two ablation needles, block is auxiliarily fixed, and play fixed ablation needle,
Ablation needle diameter 2mm in the present embodiment, long 100mm, between at a distance of 15mm.The specific reality of ablation needle 1,2 the present embodiment of ablation needle
Existing method is: the coaxial cable of ablation needle 1 and ablation needle 2 being connected with the interface of the two-way power splitter inside handle 3, simultaneously
Cooling system inside ablation needle is connected with the water tank of handle inner, the two-way function inside microwave cable interface 4 and handle 3
Divide the input interface of device to be connected, realizes the function of microwave input；Waterpipe jointing 5 and the water tank input interface phase inside handle 3
Connection, the cooling function of shank will be melted by realizing.
Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention,
Those skilled in the art can make various corresponding changes and modifications according to the present invention, but these it is corresponding change and
Deformation all should fall within the scope of protection of the appended claims of the present invention.
